“Since all terms that are defined are defined by means of other terms, it is clear that human knowledge must always be content to accept some terms as intelligible without definition, in order to have a starting point for its definitions...[and] since human powers are finite, the definitions known to us must always begin somewhere, with terms undefined for the moment, though perhaps not permanently." - Introduction to Mathematical Philosophy”

“The beginning of wisdom is the definition of terms.”

“Terms don't define our lives; our lives define our terms.”

“In philosophy class I think we finally decided that 'good' is an infinitely recursive term - it can't be defined except in terms of itself. Good is good because it's better than bad, though why it's better to be good than bad depends on how you define good, and on and on.”

“What I liked in anthropology was its inexhaustible faculty of negation, its relentless definition of man, as though he were no better than God, in terms of what he is not. But my ideas on this subject were always horribly confused, for my knowledge of men was scant and the meaning of being beyond me.”

“No manager wants success completely defined on the company’s terms. They want success defined by their own terms too.”
